Concept Check

0/5

In C, what happens when you free a structure pointer and then access its members?

Data is preserved indefinitely.

Memory is automatically reused.

No error happens.

Undefined behavior occurs.

Why does a struct with a char and an int often exceed 5 bytes in size?

Pointer dereferencing problems.

Memory fragmentation issues.

Compiler optimization error.

Due to padding for alignment.

What risk is associated with dynamically allocating an array of structures?

No risks involved.

Increased execution speed.

Automatic garbage collection.

Potential memory leaks if not freed.

In C++, how does deleting a structure with pointers affect nested pointers?

Automatic reallocation occurs.

No effect on nested pointers.

Memory is fully cleaned up.

Nested pointers may cause dangling references.

What is a common cause of segmentation faults in structure memory management?

Proper memory allocation.

Using static structures.

Accessing freed memory locations.

Compiler default settings.
